Xinhua News Agency, Hainan Wenchang, July 24 (Reporter Li Guoli, Li Yun) my country used the Long March 5 Yao 3 to carry the rocket with the Long March 5 on the 24th, and successfully launched the experimental cabin to launch.

"Therefore, the Rockets must be launched at the specified time, otherwise asking the Tianyan experimental cabin will not be able to reach the designated location.
